How to Upgrade windows server update service 3.0 SP1 to SP2

Check the WSUS version from add or remove program and make sure that it is WSUS 3.0 SP1. Select WSUS and if you click on more information you will have the below window.

If you have WSUS server SP1 installed the service pack will be already available in your network.

Open WSUS console and expand ‘Server name‘->Updates->select ‘service packs‘-> here you will be able to see the service pack for WSUS as ‘Windows server update service 3.0 SP2(KB972455)‘.

Note: You will be able to see the tab ‘service packs‘ only if you have selected the same in ‘products and classifications‘.

For WSUS SP2 to be offered on the server running WSUS SP1, the following conditions should not be true:

SQL is running remote
Server is running MOM version of SCE

If the above conditions are true and you are able to locate the WSUS 3.0 SP2(KB972455), right click on it and ‘Approve‘ it.

In order to reach the update to your WSUS server, manually run the windows update on WSUS server. Since we have approved the update for installation when you manually run windows update it will show the WSUS 3.0 SP2 as an update to install select only this and click install updates.

If the above conditions not met and you are unable to locate service pack on your WSUS server follow the below method to manually download and install

I will install it after this process so click ‘Next‘ to continue.

Now it will connect to your WSUS server which is installed for WSUS. It can be either MS internal database or SQL server. Once it is successfully connected it will fetch all the relevant data for upgrade. Click ‘Next‘ once it is successfully connected.

In order to start upgrade click ‘Next‘ and wait for this process to complete. Once it is completed successfully click ‘Finish‘.

Now it will automatically open a window to configure WSUS. Click ‘Next‘ to start configuration(You can complete the below operations later as well). The below settings will be automatically detected from your previous version of WSUS but still you can redefine these settings.

You can specify to fetch the updates directly from Microsoft or from another WSUS server. Since I dot have another WSUS server and I wish to get the updates directly from MS I have selected the first option ‘Synchronize from Microsoft Update‘. Click ‘Next‘.

If you have a proxy server in your network specify the details and click ‘Next‘.

Now you need to connect to the internet you need to apply your upstream server, proxy server settings and synchronize information about available updates so click on ‘Start connecting‘ and wait for the process to start and click ‘Next‘ once it is completed.

Specify the languages that you want to download the updates. I would recommend you to select the least number of languages since it will increase the disk space utilization. Click ‘Next‘(When you specify more than one language the updates will be downloaded in all those languages and will lead to use more disk space).

Now you need to specify the updates that are required in your network. Verify each MS products that you are using and put a tick mark on the updates that are required, Click ‘Next‘.

Select the update classifications that you require either it can be only critical updates and updates or entire classification. Select only the required classification to decrease the disk space utilization. Click ‘Next‘.
